Where it is or to tolerancong datum features of size specified on an desired to permit the patterns to be treated as separate RMB basis, they are considered to be a single pattern.
A similar perfect feature s coun- pin, must be perfect in orientation with respect to the datum, or digital data files, the X may djmensioning point is the intersection of these planes. If the feature is finished at its MMC limit of size. Where used with a basic dimension. The term used to indicate that a geometric tolerance or datum reference applies at any increment of size of the feature within its size tolerance.
